Unfortunately, some Christians have become convinced that old age serves as a sufficient excuse for a lack of service to the Lord’s work. Granted, the field of one’s service may change, but there should always remain a willingness to serve. For instance, Moses received his initial call to deliver Israel at forty years old (Acts 7:23) but did not lead God’s people out of Egypt until he was eighty (Exodus 7:7). When he died at 120 years of age, he remarked that “his eye was not dim, nor his natural force abated” (Deuteronomy 34:7). At forty years of age, Caleb received a promise from Moses concerning the possession of land in Canaan (Joshua 14:7-9). Forty-five years later, Caleb took possession by driving out the mighty Anakims (Joshua 14:10-12). Caleb did something in his old age that many of the young men could not or would not attempt (Joshua 17:13).
Each phase of life bears the marks of certain strengths and weaknesses. In youth, man has a great amount of zeal. In fact, the Bible points out that “the glory of young men is their strength.” A young man might have the fortitude, strength, and stamina to accomplish great things, but his limited knowledge hinders his ability to accomplish greatness. As time elapses, man learns from both failure and success. He obtains the knowledge and enjoys the wisdom that often eluded him during his youth. His glory no longer resides in his strength, but his beauty is now “the gray head.” The very thing that limited his ability to accomplish great things in youth is now a virtue he has achieved. The glory of his youth may have departed, but there remains hope. He has the knowledge but lacks the strength he once possessed. Fortunately, he can invest his knowledge into those who still retain their youthful vitality.
“What is the will of God for my life?” serves as one of the most oft asked questions by Christians. Unfortunately, far too many Christians complicate their search and fail in their desperate attempts to find God's will for their lives. They invest considerable time and energy looking for a field of service. All the while, they fail to notice the plain truth revealed in the scriptures concerning God's will. The truth is likely very simple. The Bible declares it good to give thanks unto the Lord and failure to do what is good is sin (James 4:17). It stands to reason, therefore, that giving God thanks serves as one of the most basic ways for man to obey the will of God. “In every thing give thanks: for this is the will of God in Christ Jesus concerning you” (1 Thessalonians 5:18). Conclusion: Giving God thanks serves as the simplest way to fulfil God's will in a Christian's life.
